Many new Lab owners are not familiar with the fact that these puppies have a natural tendency to nip and bite at human hands and arms. In fact, these little guys will put anything in their mouths that can fit. Unfortunately, some dog owners mistake this behavior as pure biting and unfairly scold and punish the animal. You must understand that Labradors are genetically designed to have an oral fixation, specifically for retrieving.

They must be trained with positive reinforcement not to mouth and bite at people's limbs. A fitting analogy is to look at a Labrador puppy the same as a piranha, but with fur. They run around with their mouths open literally hunting down anything to put in it, something, anything, whatever they can find!
